The performance of zinc-ion batteries (ZIBs) is often hindered by issues such as dendrite formation, hydrogen evolution, and limited cycling stability. 1,3-Dihydroxyacetone (DHA) not only stabilizes the anode modulating anode/electrolyte interface (AEI) but also enhances electrochemical battery through its spontaneous reversible keto-enol tautomerization, reducing concentration gradient on surface. Using a combination DFT calculations experimental characterization, regulation hydrated Zn2+ structure adsorption at AEI this additive investigated. Overall, incorporating DHA extends stability Zn||Zn symmetric to 400 h, even depth discharge 56.7% (DOD). Zn||VNNC full exhibit stable for 700 cycles 5 A g-1 with low N/P ratio (2.69), while Zn||AC capacitors (ZICs) significantly enhanced. This study evaluates potential in ZIBs dynamic characteristics molecular structures.

Abstract Despite the advantages of low cost, safety, and environmental friendliness, aqueous zinc‐ion batteries (AZIBs) encounter challenges such as zinc dendrite formation, severe side reactions, electrolyte instability. Many effective additives exhibit limited solubility in water, thus reducing their practical application potential. In this study, a dissolution‐promoting strategy is proposed by introducing citric acid (CA) to enhance dissolution aspartame (APM), resulting sulfate electrolyte. Simulations experiments indicate that CA regulates both solvation structure Zn 2+ pH electrolyte, while APM preferentially integrates into electric double layer form solid interphase with CA, thereby suppressing hydrogen evolution reactions. Consequently, zinc‐zinc symmetric cell exhibits an extended lifespan over 4,500 h at 1.0 mA cm −2 /1.0 mAh . As result, AZIBs commercial foil MnO 2 enhanced rate capability improved capacity retention (75.6%) after 2,000 cycles. This study presents novel for stabilizing anodes offers comprehensive framework addressing fundamental AZIBs, advancing next‐generation energy storage systems.

Abstract Aqueous zinc‐ion batteries (AZIBs) attract attention due to their safety and high specific capacity. However, practical applications are constrained by Zn anode corrosion, dendritic growth, poor high‐temperature adaptability induced a strong hydrogen‐bond network in aqueous electrolytes.
